Abstract

India has large coastline exceeding 7,517kms. The marine clay is found widely along the coastal corridor and it causes expensive solutions in the construction of coastal highways and building foundations. Hence, the marine clay should be stabilized to increase its strength to meet the requirements for the construction of highways and building foundations. In this paper, phosphogypsum is used as an admixture and lime is used as additive to stabilize the marine clay, thereby improving its strength, deformation and swell characteristics. Systematic and methodological process was followed involving experimentation in the laboratory under controlled conditions to study the cyclic pressures of untreated and treated marine clay as subgrade for flexible pavements.
